Definition
Geology is the scientific study of the Earth, its materials, and the
processes acting upon them.
Earth’s Relationship to the Universe
Understanding Earth’s formation, its position in the solar system, and
its interactions with cosmic forces.
Earth’s History
Examining changes over the past 4.5 billion years, including the
formation of continents, oceans, and life.
Geological Processes
Investigating internal processes (e.g., plate tectonics, volcanic
activity) and external processes (e.g., erosion, weathering) that shape
the Earth’s surface.
